Page 2 THE NATIONAL FLOOD INSURANCE PROGRAM ELEVATION CERTIFICATE PURPOSE OF THE ELEVATION CERTIFICATE The Elevation Certificate is an important administrative tool of the National Flood Insurance Program(NFIP). As part of the agreement for making flood insurance available in a community, the NFIP requires the community to adopt a floodplain management ordinance containing certain minimum requirements intended to reduce future flood losses. One such requirement is that the community"obtain the elevation of the lowest floor(including basement)of all new and substantially improved structures,and maintain a record of all such information." The Elevation Certificate is one way for a community to comply with this requirement. The Elevation Certificate is also required to properly rate post-FIRM structures,which are buildings constructed after publication of the Flood Insurance Rate Map(FIRM), for flood insurance in FIRM Zones Al-A30,AE,AO,AH,�A(with Base Flood Elevations.[BFE's]), V1-V30, VE,and V(with BFE's). In addition, the Elevation'Certificate is also needed for pre4F RM structures being rated under post-FIRM flood insurance rules. Use of this certificate does not in any way alter the flood insurance purchase requirement. The Elevation Certificate is only used to provide information necessary to ensure compliance with applicable community floodplain management ordinances, to,determine the proper flood $ insurance premium rate,and/or to support a request for a Letter of Map Amendment or Revision(LOMA or LOMR).Only a LOMA or LOMR from the Federal Emergency Management Agency(FEMA)can amend the FIRM.and remove the Federal requirement for a lending institution to require the purchase of flood insurance. Note that the lending institution may still require flood insurance. This certificate is only used to certify the elevation of the reference level of a building. If a non-residential building is being floodproofed, then a Floodproofing Certificate must be completed in addition to certifying the building's elevation. Floodproofing of a residential building does not alter a community's floodplain management elevation requirements or affect the insurance rating unless the community has been issued an exception by FEMA to allow floodproofed residential basements. INSTRUCTIONS FOR COMPLETING THE ELEVATION CERTIFICATE The Elevation Certificate is to be completed by a land surveyor,engineer,or architect who is authorize d by state or local law to certify elevation information when the elevation information for Zones Al-A30,AE,AH,A(with BFE's), V1-V30,VE,and V(with BFE's) is required. Community officials who are authorized by local taw or ordinance to provide floodplain management information may also complete this form. For Zones AO and A(without BFE's),a building official,a property owner,or an owner's representative may also provide the information on this certification. I SECTION A Property Information The Elevation Certificate identifies the building, its owner and its location. Provide the building owner's name(s),the building's complete street address,and lot and block number. If the property address is a rural route or PO box number,provide a legal description or an abbreviated location description based on distance from a reference point. SECTION B Flood Insurance Rate Map Information In order to properly complete the Elevation Certificate,it is necessary to locate the building on the appropriate FIRM,and record the appropriate information. To obtain a FIRM,contact the community or call 1-800-333-1363. The Elevation Certificate may be completed based on either the FIRM in effect at the time of the certification or the FIRM in effect when construction of the building was started. Items 1 -6.Using the FIRM Index and the appropriate FIRM panel for the community,record the community number,panel(or page) number,suffix,and Index date. From the appropriate FIRM panel, locate the property and record the zone and the BFE (or flood depth number)at the building site. BFE's are shown on a FIRM for Zones Al-A30,AE, AH, V1-V30,and VE:flood depth numbers are shown for Zone AO. Item 7. Record the vertical datum system to which the elevations on the applicable FIRM are referenced. The datum is specified in the upper right corner of the title block of the FIRM. Item 8. In A or V Zones where BFE's are not provided on the FIRM, the community may have established BFE's based on data from other sources. For subdivisions and other development greater than 50 lots or 5 acres, establishment of BFE's is required by community floodplain management ordinance. When this is the case,complete this item.

For Zones AO and A(without BFE's),a building official,a property owner,or an owner's representative may also provide the information on this certification. SECTION A Property Information The Elevation Certificate identifies the building, its owner and its location. Provide the building owner's name(s),the building's complete street address,and lot and block number. If the property address is a rural route or PO box number,provide a legal description or an abbreviated location description based on distance from a reference point. SECTION f3 Flood Insurance Rate Map Information In order to properly complete the Elevation Certificate,it is necessary to locate the building on the appropriate FIRM,and record the appropriate information. To obtain a FIRM, contact the community or call 1-800-333-1363. The Elevation Certificate may be completed based on either the FIRM in effect at the time of the certification or the FIRM in effect when construction of the building was started. Items 1 -6.Using the FIRM Index and the appropriate FIRM panel for the community, record the community number,panel(or page) number,suffix,and Index date. From the appropriate FIRM panel, locate the property and record the zone and the BFE(or flood depth number)at the building site. BFE's are shown on a FIRM for Zones Al-A30,AE, AH, V1-V30,and VE;flood depth numbers are shown for Zone AO. Item 7. Record the vertical datum system to which the elevations on the applicable FIRM are referenced. The datum is specified in the upper right corner of the title block of the FIRM. Item 8. In A or V Zones where BFE's are not provided on the FIRM,the community may have established BFE's based on data from other sources. For subdivisions and other development greater than 50 lots or 5 acres,establishment of BFE's is required by community floodplain management ordinance. When this is the case,complete this item. Page 3 SECTION C Building Elevation Information Item 1. The Elevation Certificate uses a building's.reference level as the point for measuring its elevation. Pages 5 and 6 of this Elevatic Certificate package contain a series of eight diagrams of various building types that are to be used to help determine the reference level Choose the diagram that best represents this building, record the diagram number,and use the indicated reference level to measure the elevation as requested in Items 2a-d. Item 2. Depending on the property location's FIRM Zone,complete Item 2a,2b,2c,or 2d. Use the reference level shown in the appropriate building diagram as the point of measurement. As shown in the diagram on the back of the Certificate, for all A Zones, the elevation should be measured at the top of the reference level floor. For all V Zones,the elevation should be measured at the bottom of the lowest horizontal structural member of the reference level floor. Reporting of elevations in Items 2a and 2b should be to the nearest tenth of a foot,or alternatively, unless prohibited by state or local ordinance,the reference level elevation may be"rounded down"to the nearest whole foot("rounding up"is prohibited). Item 2(a). For structures located in FIRM Zones Al-A30,AE,AH, and A(with BFE's),record the elevation (to the nearest tenth of a foov of the top of the floor identified as the reference level in the applicable diagram. Item 2(b). For structures located in FIRM Zones V1-V30, VE, and V(with BFE's),record the elevation (to the nearest tenth of a foot) of tr bottom of the lowest horizontal structural member of the floor identified as the reference level in the applicable diagram . Item 2(c). For structures located in FIRM Zone A(without BFE's), record the height(to the nearest tenth of a foot)of the top of the floor indicated as the reference level(from the applicable diagram)above or below the highest adjacent grade immediately next to the building Item 2(d). For structures located in FIRM Zone AO, the FIRM will show the base flood depth. For locations in FIRM Zone AO record the height(to the nearest tenth of a foot)of the top of the floor identified as the reference level(from the applicable diagram) above or below the highest adjacent grade immediately next to the building. For post-FIRM buildings,the community's floodplain management ordinance requires that this value equal or exceed the base flood depth provided on the FIRM. For those few communities where this base flood depth is not available,the community will need to determine if the lowest floor is elevated in accordance with their floodplain managemen ordinance. Item 3.Record the vertical datum system used in identifying the reference level elevations for all buildings. If the datum used in measurir the elevations is different than that used on the FIRM, then convert the elevations in Items 2a-d to the datum used on the FIRM, and show the conversion equation under the Comments section on Page 2. Item 4. Indicate if the elevation reference mark used appears on the FIRM. Reference marks other than those shown on the FIRM may b used for elevation determinations. in areas experiencing ground subsidence, the most recently adjusted reference mark elevations must be used for reference level elevation determinations. Item 5. Indicate if the reference level used in making the elevation measurement is based on actual construction or construction drawings Construction drawings should only be used if the building does not yet have the reference level floor in place, in which case the Elevation Certificate will only be valid for the building during the course of construction. A post-construction Elevation Certificate will be needed ona construction is complete. Item 6. Record the elevation measurement of the lowest grade adjacent to the building(to the nearest tenth of a foot). Adjacent grade is defined as the elevation of the ground,sidewalk,patio,deck support,or basement entryway immediately next to the structure. This measurement should be to the nearest tenth of a foot if this Certificate is being used to support a request for a LOMA/LOMR. SECTION D Community Information Completion of this section may be required by the community in order to meet the minimum floodplain management requirements of the NFIP. Otherwise,completion of this section is not required. Item 1. The community's floodplain management ordinance requires elevation of the building's"lowest floor"above the BFE. For the vast majority of building types,the reference level and the lowest floor will be the same. if the community determines that there is a discrepancy, record the elevation of the lowest floor. Item 2. Enter date. These terms are defined by local ordinance. SECTION E Certification Complete as indicated. The Elevation Certificate may only be signed by a land surveyor,engineer,or architect who is authorized by state or local law to certify elevation information when the elevation information for Zones Al-A30,AE. AH,A(with BFE's), V1-V30, VE, and V (with BFE's) is required. Community officials who are authorized by local law or ordinance to provide floodplain management information may also sign this certification. In the case of Zones AO and A(without BFE's), a building official,a property owner, or an owner's representative may sign this certification. Certification is normally to the information provided in Sections B and C. If the certifier is unable to certify to the selection of reference level diagram 6, 7 or 8 (Section C, Item 1), e.g.,because of difficulty in obtaining construction or building use information needed to determine the Distinguishing Feature(s), the certifier must list the Feature(s) excluded from the certification under Comments on Page 2. The diagram number used for the Reference level must still be entered in Section C. Item 1. Page 4 INSTRUCTIONS The following 8 diagrams contain descriptions of various types of buildings. Compare the features of your building with those shown in the diagrams and select the diagram most applicable. Indicate the diagram number on the Elevation Certificate (Section C, Item 1) anc complete the Certificate. The reference level floor is that level of the building used for underwriting purposes. NOTE:In all A Zones,the reference level is the top of the lowest floor;In V Zones the reference level Is the bottom of the lowest horizontal structural member(see diagram on page 2).

An area so enclosed is not secure against forceable entry. "" It the area below the lowest floor is fully enclosed. then a minimum of two openings are required with a total net area of at least one square inch for every square foot of area enclosed with the bottom of the openings no more than one foot above grade. Alternatively, certification may be provided by a registered professional engineer or architect that the design will allow equalization of hydrostatic flood forces on exterior walls. If neither of these criteria are met, then the reference level is the lowest grade adjacent to the structure. Page 6 .':U.S GOVERNMENT PRINTING OFFICE 1990 -_i-un: ,'li�.,li
